Repairing a chip on a quartz countertop can seem daunting, but with the right materials and techniques, it can be an easy DIY project. Quartz is an engineered stone made from crushed quartz bound together with resin, making it durable and low-maintenance. However, it is not completely impervious to damage. Follow this step-by-step guide to repair quartz countertop chips and have your countertop looking brand new again.
What You’ll Need
- Clear epoxy resin designed for countertops
- Mixing sticks
- Mixing cups
- Sandpaper (120 to 220 grit)
- Isopropyl alcohol
- Putty knife or scraper
- Gloves and safety glasses
Prep the Damaged Area
Before repairing the chip, you need to properly prep the area. This will help the epoxy resin adhere and create an invisible repair.
- Clean the area thoroughly with isopropyl alcohol to remove any dirt, grease or debris. Allow to fully dry.
- Use sandpaper to rough up the surface of the chip and surrounding area. This helps the epoxy resin bind. Go in a circular motion and blend the edges.
- Clean the area again with isopropyl alcohol and allow to fully dry.
- Use tape to mask off the area around the chip. This keeps excess resin from getting on the countertop surface.
Mix and Apply Epoxy Resin
Follow the epoxy resin instructions carefully to achieve the right mixture and cure time.
- Mix the resin and hardener as directed, using equal parts. Stir thoroughly with a stick for 2-3 minutes.
- Pour the epoxy into the chip, slightly overfilling. Spread smoothly and evenly with a putty knife.
- Allow the epoxy to become tacky, usually 10-15 minutes. This helps remove air bubbles.
- Once tacky, use the putty knife to scrape off any drips and blend the edges. Remove any tape.
- Allow the resin to fully cure as directed, usually 24 hours.
Sand and Polish
Once fully cured, blend and polish the repaired chip using sandpaper and a rag:
- Wet sand with 220 grit sandpaper to smooth the surface. Sand in a circular motion.
- Switch to 400 grit sandpaper and continue wet sanding to blend and polish.
- Clean the area and dry thoroughly.
- Use a clean, dry rag to hand polish and remove any fine scratches.
The chip repair should now appear smooth and blended. Quartz countertops are good as new! Be sure to take precautions to prevent chips in the future. Use cutting boards, avoid hard impacts, and don’t place hot pans directly on the surface.
FAQs About Repairing Quartz Countertop Chips
What’s the easiest way to repair a chip?
Clear epoxy resin designed for countertops offers the simplest DIY repair method. It cures smooth and crystal clear for an invisible fix.

It’s not recommended. Super glue can dry cloudy and the repair will be obvious. Epoxy resin is formulated to cure crystal clear and hard.
How long does the epoxy take to cure?
Most countertop epoxy resins take 16-24 hours to fully cure. Some quick-set formulas take as little as 6 hours. Always follow manufacturer directions.
Should I use the chip piece that broke off?
You can, but matching the color and pattern can be tricky. Clear epoxy resin provides a seamless appearance.
Can I sand and polish the repaired area?
Yes, light sanding and hand polishing with a rag will help blend the edges and remove any imperfections after the epoxy has cured.
Will the chip repair stand up over time?
When done properly, epoxy chip repairs are extremely durable and last for years. The repair can withstand heavy use and cleaning.
Should I call a pro for large chips or cracks?
For minor chips, DIY epoxy repair is easy. But for deep cracks or large damaged areas, it’s best to have a countertop pro make the repair.
Fixing a chip or crack in a quartz countertop is a simple DIY project that can make the countertop look brand new again. With the right epoxy resin, preparation, and sanding techniques, the repair will be virtually invisible and stand the test of time. Pay special attention to prepping the damaged area to ensure the epoxy bonds properly. And always follow the product instructions closely.
